Building ventures
that matter.
Helping others
do the same.

Technology is the most powerful tool we have. The question is what we point it at.

David Lais

About

I'm David — entrepreneur, builder, and occasional troublemaker in industries that need one.

I've spent 20+ years using technology to shift how people relate to money, consumption, and the planet. It started as a teenager with a laptop and too many ideas — I taught myself to code, captivated by this wonder of a technology that lets you create something from nothing.

Twenty years later, we have a new, equally (if not more) transformative force in AI. So I asked it to introduce me. Below is what Claude Sonnet 4.6 said when I gave it the prompt — generated once, kept honest. We update it when the story changes.

Hey Claude (Sonnet 4.6): I am David Lais — how would you describe in a few short paragraphs who I am and how I can help others with my knowledge and network, especially through my investment company LTVI?

Certainly not the way I would describe myself, but this is the "real deal." One small correction though: Clarity AI acquired ecolytiq in 2025, not 2024. Oh, and it's not me building Nuri Tales — that's my wife's venture. I'm just helping ;)

Consulting

Working with founders
who mean it.

I advise a small number of entrepreneurs building technology for genuine social or environmental impact. Not advisory-board cosmetics. Real work — from early product thinking to go-to-market strategy, fundraising narrative to team building.

I bring what I've learned from 20+ years in fintech, building climate tech that reached millions of users, and navigating the particular challenge of selling mission-driven products to large institutions.

I only take on engagements I can meaningfully contribute to. If you think there's a fit, I'm easy to reach.

If you're building something at the intersection of technology and positive impact, and you think I might be useful — reach out. The conversation is free.

Get in touch

Let's build
something
that matters.

Whether you're a founder looking for a thinking partner, or someone who wants to talk about conscious consumerism — I'm genuinely open to conversations.

LTVI is not a venture fund nor a business angel network — I am a venture builder and investor, in projects I truly believe in. If my work with LTVI resonates with you, I'm always happy to connect over shared ideas.
